I was born in the beautiful city of Como, Italy.

I grew up with three brothers, and while playing Basketball and Ultimate Frisbee I became an Engineer and a Theoretical Physicist. In 2008 I married my lovely wife and in 2011 we had our first child. I have lived in Italy, France, Singapore, Australia and Switzerland, and I have been blessed to meet a great number of fascinating people.

Two of my greatest passions are teaching and research. I had the chance to pursue them during my PhD and postdoc years at the National University of Singapore, the Australian National University, the Centre for Quantum Technologies in Singapore, at the Ecole Polytechnique in Paris and at the University of Geneva.

I am inspired by the supervisors, teachers, colleagues and students with whom I had the good fortune to work.


Research Interests

I am interested in the physics of complex systems. The main reason is that the interplay of the different components of a system allows the emergence of fascinating phenomena such as solitonic waves, glass-like dynamics, negative differential thermal conductance and superconductivity (to name a few).

The possible applications are too many to mention, from telecommunication technology to microchips or material engineering … the limit is our imagination!

My focus is mainly on the study of the dynamics of complex quantum systems because (i) the quantumness of the systems makes them more interesting and richer in potentialities and (ii) it is now possible to realize and study them with a remarkable degree of control as a result of experiments with ultracold gases.
